ADDING- MAQHINE.

. Application filed m 11, 1925. Serial no. 29,457.

This invention relates to improvements in number setting up devices for adding machines and recording machines, the setting up mechanism being the mechanism that 1: determines the distance which the parts concerned travel to register or print the number selected, such registering being effected by additional means after the setting up mechanism has come-torest in set up position.' L I An object of the invention is to simplify the mechanism referred to, thereby contributing to the simplicity of construction, more particularly of machines of comparatively small size and light weight.

Another object of the invention is to make the operation of a machine, employing'a setting up device, other than what is known as a keyboard, easier for the operator by lessen' ing the mental effort required in selecting and engagingthe part of the machine necessary-to effect the selected number reaching its operative position, thus also contributing to the speed of the machine.

The foregoing and other objects of the invention, together with means whereby the same may-be carried into efiect, will be best understood from'the following description 3 of certain forms "or embodiments thereof illustrated in the accompanying drawings wherein the invention is embodied in an adding'and recording machine. It will be .understood, however,- that the particular constructions described and shown have been chosen for illustrative purposes merely, and

that the invention as defined by the claims hereunto appende may be otherwise practised without departing from the spirit and scope thereof.

In said drawingsr Fig. 1 is a vertical section showing certain parts of an adding and recording machineembodying the present invention. Fig.2 1S aviewof setting up members on line 2 2 Fig. 1 in direction of arrows.

the post 4 by the operator. .The plate 6 may thereof, is a slotted bar l and further to the rear of themachine is a second transverse slotted bar 2, these bars in connection with other suitable parts, connecting the two side frame parts of the machine.

At the upper part of the side frame parts is another transverse slotted bar 3, which serves to hold in place the upright bars or 7 posts and guides 4 and 5, the lower ends of which being supported respectively in the slotted bars 1 and 2. I a i A. plate 6 has fastened. to it the brackets 7 and 8 which form bearings for the plate when it is mounted on the upright post 4 and permit it being moved alongthe post 4, Figs. 1, 3, 4. Attached to the plate 6 at sub stantially right angle is a number segment 11 upwardly and downwardly movable on the guide 4 and bearing a series of numeral digits, in this instance O-to 9. Theplate 6 is 1n effect a setting up key and extends beyond the number'segment 11 and the edges are in form of a rack'having gear teeth 9, 13, which correspond with the series .of numeral digits and the teeth 9 form stations to receive an object, a stylus, for instance, with which the plate may be moved down along 96 be called the setting up member for convenience in referring to. it. The teeth 9 "are. preferably pointed so as to offer as much 1 space as possible where the stylus enters.

The numeral digits on the number segment 100 or plate 11 are arrangedvertically, that is,

one above the other, and instead of all be I ing in one line or column, they are staggered, as; all the odd numbers in the-left column and all the-even numbers in right column. Thus arranged the space between the num-. bers of a column is twice as large as it would be if all the odd and even figures were in, one column and 'with such arrangement larger figures may be usedin av comparatively small machine thereby making the reading of them easier and contributing to the speed of the machine. In machines now on the market where a stylus is used for setting up figures to be added, the numerals are all in one vertical line and as these machines are of small size, the numerals are also small and call for great care from the operator in selecting them. By making the teeth 9 pointed and arranging them at practically right angle to the number plate 11, a stylus 12 that is flat and bifurcated Fig. 4 is readily directed into the teeth with little mental effort by the operator and through the two prongs of the forked end is held against slipping out of the teeth sidewise.

Fixtending transversely of the machine in front of the setting up members 6 is a slotted bar 14, Figs. 1, 2. which serves as a stop for the stylus when the latter has moved the setting up member the desired distance, Fig. 1, 12 in dotted lines. The stop 14 prevents overthrow of the setting up member when it is moved rapidly as the stylus between two teeth 9 and bearing on the stop 14 locks the setting up member against further movement downwards and the weight of the operators hand. prevents it rebounding after sudden stop and remaining in the rebound position. The slots insure that when the stylus is at the bottom of the angle between two teeth it will at that point also hear on the stop 14:, so that the setting of each member or key 6 is accurate.

The member 6 may be provided with a lip or key-to'p.1O which can be used by the operator for depressing the member 6 when operating without a stylus.

The rear edge of the setting up member 6 is formed with gear teeth 13 which mesh with a gear wheel 21 mounted on a cross rod 22. These teeth or racks 13 constitute means for the positioning of printing mechanlsm. The gear 21 meshes with the teeth 20 of a shuttle 18 which is mounted on post 5 to slide up and down. The rear edge of the shuttle 18 is provided with rack teeth 19 which are engaged by an aligning pawl 15 pivotally mounted on cross rod 16 and held in contact with the teeth 19 through the spring 17, the function of the pawl 15 being 7 to prevent accidental movement of the parts including the setting up member 6, which through lts gearing to the shuttle 18 moves n unison with the shuttle.

cross bar 23 forms a bail With its side [parts 24 fastened to a shaft 25 which is mounted to rotate in the frame side parts, A. and extends outside of the frame parts.

On, the left end of the shaft 25 outside of 3 ,the left frame side part is fastened an arm 26 carrying a pin or anti-friction roller 27. A shaft 28, also mounted to rotate in the frame side parts and extending beyond said side parts has fastened to it near the outer end a cam 29 which engages the pin 27, thus when the shaft 28 is rotated forwardly the cam bears on the pin 27 and causes the bail 23 to move upwards when the bail will move back to normal any setting up member that had been brought down to set up a number. An operating handle 30 Fig. 1 in dotted lines, is attached to the shaft 28 on the right hand side of the machine.

A number wheel 31 with its gear wheel 32 constitutes an adding wheel and the orders of said wheels constitute an accumulator which is carried in a rocking frame 33 pivoted at 34. Fig. 1. There is an adding wheel for each order, the whole constituting an accumulator. The Wheel 31, by this number is meant the whole adding wheel, is brought into engagement. with the teeth 9 of the setting up member 6 when the wheel frame 33 is oscillated at the proper time as is usual in adding machines. The mechanism for controlling and actuating the adding mechanism may be of any suitable or well-known construction and need not, therefore, be herein shown or described.

The shuttle 18 is provided with a rearwardly extending finger 18 which carries a type bar or segment 35 pivoted at 18 In printing the type bar 35 is brought upward to the printing line opposite the platen as when the setting up member 6 is brought down to set up a number. As with the adding wheel, the type bar forms no part of this invention, therefore any well-known and suitable means may be used for effecting the printing without its being shown and described herein.

It will, of course, be understood that the single setting up member and co-operating parts, including the adding wheel and the type bar shown in Fig. 1 represent only one of several such elements or mechanisms of an adding and recording machine and that the complete machine will contain as many setting up members and cooperating parts as may be necessary according to the desired capacity of the machine.

The operation of the machine is as follows: Assuming that the numeral 7 is to be added and recorded, the operator inserts the stylus 12 in the space between two of the teeth 9 of the setting up member 6 which is in line with the Figure 7 on the number segment 11, then draws down the setting up member until the stylus is stopped against the cross bar 14, when the stylus is then removed. As the setting up member is moved downward its shuttle 18, being geared through gear wheel 21 to the member 6, will move upward and bring the type character corresponding to the number selected in the setting up parts to the printing position when the stylus is stopped against the cross bar 14. In the present instance the number The aligning pawl 15 will hold the parts On further rotation of the shaft 28, the cam 29 will depress the arm 26 through the pin 27 and thereby raise the bail 23, which will pick up and push .back to normal the setting up member 6 which had been set up fora 7 During the ascent of the setting u member it will rotate the adding wheel 31 In adding direction. When the bail 23 has returned what setting up member that had been in set up position to normal position, the handle may be returned to its normal position, during which travel it may throw the adding wheel out of mesh with the setting up member and-accomplish any other functions that may be necessary.

In taking a total the gear wheels 32 are first thrown into engagement with the racks 9' in a known manner, and then each of the key elements 6 is depressed, preferably by means of the key-top or lip 10, which causes 7 each addingwheel' to be turned to zero, the

wheels being stopped by the usual or suit- I able zero stopping means and then the parts are ready for the printing of the total, and when. the accumulator is thrown out of engagement with the 'key elements it is in a cleared condition.

While I have shown and described an adding and recording machine employing sliding setting up members with the number segments attached to and movable with the setting up members and the rack or station part of the setting up member at substantially rightangle to the number segment, my

invention .is not limited in this regard and these parts may be varied as, for instance, shown in Fig. 5 where theparts- 37 are the equivalent of the teeth 9 of a setting up member and are in a plane with thenumber segment; Fig. 6 where the part, .38 is the equivalent of comb or transverse bar 3 and the continuation 38 is the equivalent of the number segment 11 and the further extension 38 is the equivalent of the cross bar 14. In this construction the number segment 38 is stationary and'only the part 39, which is the equivalent of the. settingv up member 6, moves; Fig. 8 where part 40, 40", 40 is the equivalent of part 38, 38?, 38 of Fig. 7 and part 41 is the equivalent of the setting up member 6 and is pivoted at 42 instead of being mounted to slide on an upright post.
